Title: Regulating the Temperature of Simultaneously Extruded Plastics Blow Moulding Parisons
IPC: B29C48/695
Filed: 1980-10-01
Abstract: Plastics material flowing towards parison extrusion nozzles along ducts 2, 3, and 16 to 19 of a distributor, is temperature-controlled approximately to the same required temperature along the separate paths defined by the ducts, by means of a temperature- controlled i.e., heated or cooled medium, circulated along at least one section of the length of the respective flow path along the wall of the said flow path. Control may be effected from measurement of the plastics material temperature along the length section, and alteration of the flow circulation rate or of the temperature of the medium as measured at the inlet or outlet of the ducts. The medium is circulated by a circuit comprising cooling and heating means 21, 22, a pump 23 and temperature measuring means 9, and is circulated through helical or axially parallel ducts 5 or 27, 28, in sleeves 4 or 20. Heating and cooling medium i.e. oil, may be circulated through alternate groups of ducts 5 or 27, 28 around a path, or the alternate ducts may respectively contain electrical heating elements and the medium. <IMAGE>

Title: Roller retainer for cam-actuated brake assembly
IPC: F16D65/22
Filed: 1980-11-20
Abstract: The cam 19 acts on dual web shoes 14 via rollers 20 retained in recesses in the webs 31 by roller retainers 40 each comprising a member preferably formed from spring wire to provide two substantially parallel legs 42, 44 with a tang 46, 48 at the end of each leg and a manual grip 41 intermediate the legs. The tangs 46, 48 are seated in apertures 36 provided in webs 31 and portions 50, 52 of the member intermediate the manual grip and the tangs extend only partially around the roller so the manual grip and the tangs are disposed on the same side of a reference plane n parallel to the legs 42, 44 and passing through the axis of the roller. This enables the retainer to be rotated about the apertures thereby allowing the roller to be safely removed from the brake shoe while the shoe remains in the assembly without the use of any tools. Roller retainer may also be formed from synthetic material, stamped from steel plate, or fabricated from combination of separate elements. <IMAGE>

Patent GB-2083308-A (GB)
Title: Voltage generator for testing firing of ignitor
IPC: F02P17/12
Filed: 1981-08-11
Abstract: The generator produces a square wave voltage that is applied across a parallel circuit comprising a first capacitor 18 and a series arrangement of a second capacitor 19 and diodes 24. An inductance 20 and a thyristor 21 are connected across the first capacitor 18, in series. When the thyristor 21 is rendered conductive the voltage across the diodes 24 becomes the sum of the voltage across the capacitors 18 and 19, this voltage being applied across the igniter 4. Switching of the thyristor 21 is controlled such that the voltage is applied to the igniter 4 in increasing steps of 25 volts until the breakdown occurs at the same voltage five times in succession. The voltage across the igniter 4 is determined by applying it across a capacitive divider, one capacitor being discharged in steps, and the number of steps required to reduce the voltage to a reference value is counted. <IMAGE>

Title: Television line standard conversion
Inventor: HULYER MICHAEL GEORGE
IPC: H04N7/01
Filed: 1983-01-17
Abstract: An analog 625-line signal is applied to input 1 and converted to a digital signal A at 2. This signal is then delayed by delay means 3, 7, 8 to produce delayed signals C,D,B. Delay devices 3, 8 producing delays of one field period less half a line period and 7 a line period delay Signals C, D are averaged by circuit 12 while A and B are averaged by circuit 9 a movement detector 17 operates switch 11 so that if no movement is detected interpolation is carried out between adjacent lines of the same field (C,D) where as if movement is detected interpolation is carried out between the same lines of adjacent frames. The signal E is then supplied to a conversion arrangement 5 to provide the 1249-line signal I with the same field and frame rate. This signal is then interpolated at line rate 21 converted to analogue form 22 and applied to output 23. Thus the adverse effect of motion in the picture is reduced. <IMAGE>

Title: Electronic apparatus for metering and measuring electrical energy consumption in a manner which simulates the same measurement as effected by a rotating disc electromechanical meter
Inventor: HUTT PETER RICHARD
IPC: G01R21/133
Filed: 1983-07-23
Abstract: Apparatus whose measurement means consists solely of electronic components, measures the power taken by an electrical load connected to an alternating source of electricity supply in such a manner that the power sensed or energy accumulated is in agreement with the same measurements as performed by a conventional rotating disc electromechanical meter. Fundamental frequency filtering means 3, 6 when applied to either one or both supply voltage and load current ensure that the electronic circuitry performs the appropriate measurements in determining power consumption. A single sample per mains cycle applied to load current and supply voltage is sufficient to measure power consumption, energy consumption accumulation, and produce accumulated energy pulses appropriate to measurement of real power, true power and volt-ampere power consumed by the load. <IMAGE>

Title: Conveying systems
Inventor: CHALU TERENCE
IPC: B65G17/20
Filed: 1983-07-28
Abstract: In an overhead conveying system two hangers carry between them an elongate bar 13 which in turn carries the work piece or work pieces; and one of the hangers, 11, engages the bar via a detent 28 such that there is normally no relative motion between the hanger 11 and the bar 13 as they travel along the conveyor, but when the distance between the hangers needs to be altered, e.g. for travel around a bend, a suitably stationed arm, past which the hangers travel, automatically disengages the detent 28 from a recess 32 in the bar 13 to permit the latter to slide relative to the hanger 11. The detent may be spring (as shown) or gravity biassed into contact with the bar, and the hanger may have a second arm which acts to hold the detent out of contact with the bar once displaced from the recess. Rollers 22,23,24,25 may support the bar 13 on the hanger 11. <IMAGE>

Title: Tube wall thickness
Inventor: MONNO ASAO
IPC: G01B15/02
Filed: 1983-09-07
Abstract: A radiation source 21 emits parallel beams of radiation (e.g.  gamma - rays) which pass through a tubular part or pipe 11, whose wall thickness is to be measured, these radiation beams then being detected by a detector 22. The length  lambda  of the radiation source 21 and the radiation detector 22 is greater than the outside diameter D of the pipe 11, so that the radiation passes through the entire cross- section of the pipe. The average wall thickness of the pipe can be determined from the amount of attenuation of radiation which is detected by the detector 22. The wall thickness measurement can be performed on the pipe 11 while the latter is being conveyed by rollers 9. <IMAGE>
